Facilities and Equipment

The mm-wave laboratory includes 54 m2 of a well equipped RF lab including a number of high quality instrument and an ALMA compatible cryostat. The machine shop is a 80 m2 facility where we fabricate microwave devices and support the design and implementation of test set-ups. It includes a CNC milling machine of 1 micrometer of accuracy. 27 m2 are used for storage, cryogenic and air compressors.
